*Cough cough* I remember that *cough cough*...
Unix systems in those days were broken in subtle ways; we once broke into
a Gould (marketed as the most secure box on the planet[*]) by
social-engineering a marketoid (we tricked him into running a custom "ls"
or something). "Thank you Sir, and we've just broken into your Gould;
there's the root prompt".
They never did pay us our bounty, because we "cheated" :-)
